RESUMO

OBJETIVO. Determinar los conocimientos, actitudes y prácticas de la pediculosis capitis en padres de niños de 5 a 12 años del Centro educativo Academia Franciscana del Distrito Educativo 01-03, Barahona, República Dominicana, en el periodo enero a mayo 2018. DISEÑO. Se realizó un estudio de tipo descriptivo de corte transversal, donde la unidad de análisis fueron los Padres y Madres de escolares entre 5 a 12 años del Centro educativo Academia Franciscana, en el distrito educativo 0103 Barahona, República Dominicana. Se tomó un universo de 50 padres, se obtuvo autorización para la realización de este estudio por las autoridades del centro educativo y se les notificó a todos los participantes mediante un consentimiento informado. RESULTADOS. El 73 % de las personas reconocen que ha habido algún caso de pediculosis de la cabeza en su familia, evidenciando que la pediculosis es muy frecuente en la población. Más de la mitad de los padres consideran que los piojos se contagian cuando vuelan de cabeza a cabeza así como que falta de higiene favorece el contagio por piojos; estos datos evidencian la falta de información sobre la pediculosis capitis. CONCLUSIÓN. La mayoría de los casos tenían poco conocimientos sobre el tema, también se destacó el estigma social que supone para algunas personas estar frente a una infestación por Pediculosis capitis y el uso de productos de elaboración casera es una de las prácticas más realizadas

RESUMO

BACKGROUND: Head louse, Pediculus humanus capitis, is an obligatory blood-sucking ectoparasite, distributed worldwide. Phylogenetically, it occurs in five divergent mitochondrial clades (A-E); each exhibiting a particular geographical distribution. Recent studies suggest that, as in the case of body louse, head louse could be a disease vector. We aimed to study the genetic diversity of head lice collected in the Democratic Republic of the Congo (DR Congo) and to screen for louse-borne pathogens in these lice. METHODS: A total of 181 head lice were collected from 27 individuals at the Monkole Hospital Center located in Kinshasa. All head lice were genotyped and screened for the presence of louse-borne bacteria using molecular methods. We searched for Bartonella quintana, Borrelia recurrentis, Rickettsia prowazekii, Anaplasma spp., Yersinia pestis, Coxiella burnetii and Acinetobacter spp. RESULTS: Among these head lice, 67.4% (122/181) belonged to clade A and 24.3% (44/181) belonged to clade D. Additionally, for the first time in this area, we found clade E in 8.3% (15/181) of tested lice, from two infested individuals. Dual infestation with clades A and D was observed for 44.4% individuals. Thirty-three of the 181 head lice were infected only by different bacterial species of the genus Acinetobacter. Overall, 16 out of 27 individuals were infested (59.3%). Six Acinetobacter species were detected including Acinetobacter baumannii (8.3%), Acinetobacter johnsonii (1.7%), Acinetobacter soli (1.7%), Acinetobacter pittii (1.7%), Acinetobacter guillouiae (1.1%), as well as a new potential species named "Candidatus Acinetobacter pediculi". CONCLUSIONS: To our knowledge, this study reports for the first time, the presence of clade E head lice in DR Congo. This study is also the first to report the presence of Acinetobacter species DNAs in human head lice in DR Congo.

RESUMO

PURPOSE: To report the clinical features and outcomes of toxic keratitis after application of powdered custard apple seeds for hair washing for head lice infestation. METHODS: Retrospective review of all patients with toxic keratitis after application of powdered custard apple seed for head lice infestation during the time period from January 2015 to December 2017. Demographic details, clinical features, and visual outcomes were documented. RESULTS: Thirty-one eyes of 19 patients with toxic keratitis after application of crushed custard apple seeds for head lice infestation were included in the study. Eighteen females and 1 male with a median age of 14 years [interquartile range (IQR) 12-34 years] presented with severe epiphora, congestion, photophobia, and defective vision (median logMar visual acuity 0.4, IQR 0.2-0.8) after application of custard apple seed powder for hair washing. Ten eyes (32.2%) had an epithelial defect (median size 9 mm, IQR 5-12 mm), and 21 (67.7%) eyes had punctate epithelial erosions. All the patients were treated with topical antibiotics, and at 3 days follow-up, all of them had resolution of symptoms and signs with a median logarithm of the minimum angle of resolution (logMAR) visual acuity of 0 (IQR 0-0.2). CONCLUSIONS: Health education about the harmful effect of this traditional practice for head lice infestation will prevent further similar events.

RESUMO

Caprine pediculosis is an ectoparasitic disease of great concern among goat farmers in India. It may be caused by either sucking lice or chewing lice; the latter one results in severe skin lesions, leading to production loss. This study evaluated the effectiveness of the macrocytic lactone drug, ivermectin, administered via subcutaneous injection, against chewing lice Bovicola (Damalinia) caprae infestation in naturally infested goats. The study was conducted on 20 goats with severe B. caprae infestation. Animals of group A (n = 10) were treated using a single dose of ivermectin (200 µg/kg body weight) subcutaneously and animals of group B (n = 10) underwent placebo therapy using normal saline. The animals were examined on days 0, 3, 7, 14, 21, 28, 42 and 56 for lice counts. There was 100% elimination of lice in all animals of group A and effective protection from re-infection remained at least for 21 days. Considerable improvement in haematological parameters was also observed by day 21. Based on this study, ivermectin injected via a subcutaneous route can be used effectively for the therapeutic and prophylactic management of chewing lice infestation in goats maintained under an extensive grazing system.

RESUMO

Antarctophthirus microchir is a sucking louse species belonging to the family Echinophthiriidae and has been reported to parasitize all species of the subfamily Otariinae, the sea lions. Former studies on this ectoparasite mainly required fixation, immobilization, or death of host species and especially examinations of adult male sea lions are still very rare. Between March and May 2018, adult individuals of a unique "urban" bachelor group of South American sea lions (Otaria flavescens) living directly in the city of Valdivia, Chile, were studied regarding their ectoparasite infestation status. For first time, a non-invasive method in the form of a lice comb screwed on a telescopic rod and grounded with adhesive tape was used for sample taking process. Overall, during combing different stages of A. microchir were detected in 4/5 O. flavescens individuals, especially at the junction between the back and hind flippers. Our findings represent the first report of A. microchir infesting individuals of this synanthropic colony and fulfilling complete life cycle in a sea lion group despite inhabiting freshwater and in absence of females/pups. Our "telescopic lice comb apparatus" offers a new strategy to collect different stages of ectoparasites and a range of epidermal material, such as fur coat hair and superficial skin tissue for a broad spectrum of research fields in wildlife sciences in an unmolested and stress reduced manner.

RESUMO

PURPOSE: To describe a new genus and two new species of chewing lice from Southeast Asian trogons (Trogoniformes). These lice belong in the Philopterus-complex. METHODS: Slide-mounted lice were examined in a light microscope, illustrated by means of a drawing tube, and described using standard procedures. RESULTS: The new genus and species were successfully described. CONCLUSIONS: The genus Vinceopterus n. gen. is described from two species of Southeast Asian trogons (Trogoniformes: Harpactes). It presently comprises two species: Vinceopterus erythrocephali n. sp. from three subspecies of the Red-headed Trogon Harpactes erythrocephalus (Gould, 1834), and Vinceopterus mindanensis n. sp. from two subspecies of the Philippine Trogon Harpactes ardens (Temminck, 1826). Vinceopterus belongs to the Philopterus-complex, and thus likely constitutes a genus of head lice. Vinceopterus is the second new genus of chewing lice discovered on Southeast Asian trogons in recent years, the first genus of presumed head lice on trogons worldwide, and the fifth genus of chewing lice known from trogons globally. A translated and revised key to the Philopterus-complex is provided, as well as notes on the various chewing lice genera known from trogons.

RESUMO

Bedbugs, mites, and scabies are ectoparasites that commonly affect humans. Bedbugs (Cimex species) were once rare in the United States but are now common. They cause intensely pruritic lesions on areas of exposed skin. The bites are highly allergenic and can cause asthma exacerbations or anaphylaxis. Management of bedbug bites involves symptomatic relief of itching and dealing with patient anxiety. Identification and elimination of infestation are most important. Another ectoparasite of concern is lice (Pediculus and Pthirus species), which causes head, body, and pubic infestations. Patients can experience hypersensitivity to the saliva of lice, but such symptoms often do not develop until several weeks after infestation. Diagnosis involves identification of nits (ie, eggs) or lice on the skin or hair. Several pediculicides are used for management but wet combing without use of pediculicides may be more effective. A third common ectoparasitic infestation, scabies (ie, infestation with the mite Sarcoptes scabiei), affects 5% of the world's population. Patients present with pruritic lesions in skin folds, finger webs, and areas in which clothing is tight. The diagnosis can be confirmed with dermatoscopy or microscopy. Management involves use of permethrin cream, oral ivermectin, or benzyl benzoate.

RESUMO

Pediculosis, that is the infestation of humans with Pediculus humanus capitis (head lice), poses a worldwide problem that is as old as mankind itself. Over the centuries, man has developed a variety of remedies, all of which have ultimately culminated in the use of chemical agents. Some of these remedies are known to produce successful results. A large portion of the effective remedies used to kill lice and their eggs contain insecticides, but there is an increasing number of reports of head lice populations revealing an increased resistance. This study presents an alternative treatment approach, the efficacy of which is based on physical effects. Cold atmospheric pressure plasmas have successfully shown their formidably wide application range within the field of plasma medicine. This study presents a plasma device in its current stage of development that is engineered as a consumer product to enable an alternative physical and insecticide-free option for the treatment of pediculosis. An efficacy study concerning different developmental stages of P. humanus humanus is presented. P. humanus humanus was chosen as a substitute test organism for P. humanus capitis due to possible laboratory rearing and high anatomic similarity. The study shows how a single stroke of the plasma device over a hair strand (approximately 22 cm in length with a weight of 1.5 g) led to mortality rates of 68.3% (50.0; 79.7) (95% CI) in the juvenile test group, a mortality rate of approx. 67.7% (54.9; 78.8) (95% CI) in the female test group, and approx. 46.7% (28.3; 65.7) (95% CI) in the male test group. When single eggs were introduced directly into the plasma for approx. 1 s, younger eggs (0⁻2 d) showed a higher mortality of 66.7% (42.7; 82.7) than the older (4⁻6 d) eggs, with 16.7% (5.6; 34.7) (CI). Furthermore, the results of a risk assessment of the device are described. The article concludes with necessary handling instructions as well as further developmental steps, derived from the results of the efficacy and the risk assessment study.

RESUMO

During World War I, a mysterious new disease affected soldiers on both sides of battle field. The first reports described a relapsing fever of unknown origin with body lice being suggested as the vector. The outbreak affected >1 000 000 people, mostly soldiers fighting in front-line trenches. Shortly afterward, the illness was known as Trench fever, of which the causal infectious agent is currently classified as Bartonella quintana.

RESUMO

BACKGROUND: There is a need for better control of head louse infestations. Abametapir is an inhibitor of metalloproteinases critical for louse survival and egg development. The efficacy of abametapir lotion, 0.74%, was assessed for its ability to clear head louse infestations after a single application. METHODS: Two randomized, double-blind, multicenter, vehicle-controlled studies were conducted in subjects aged 6 months and older to compare the effectiveness of abametapir lotion versus vehicle control for eliminating head louse infestations without nit combing. Abametapir lotion was applied to dry hair for 10 minutes on day 0 and then rinsed with water. The primary endpoint was the proportion of index subjects (youngest household member with ≥ 3 live lice at screening) in the intent-to-treat population who were louse free at all follow-up visits through day 14. Older household members with one or more live lice at screening were designated as nonindex subjects and treated as per the index subject within their household. RESULTS: In the intent-to-treat population (index subjects, N = 216), 81.5% of subjects treated with abametapir lotion were louse free through day 14 after a single treatment, versus 49.1% with vehicle (P < 0.001). For the combined index and nonindex population (N = 704), 85.9% were louse free through day 14 in the abametapir group, versus 61.3% in the vehicle group (P < 0.001). The most frequently reported adverse events were erythema (4.0%), rash (3.2%), and skin burning sensation (2.6%). CONCLUSION: Abametapir lotion, 0.74%, was effective at clearing active head louse infestations through day 14 in subjects aged 6 months and older. All adverse events (including one serious but unrelated to study drug) resolved uneventfully.

RESUMO

Ten new species of chewing lice in the genus Brueelia Kéler, 1936, are described from hosts in the families Paridae, Regulidae, and Sittidae. They are: Brueelia johnsoni n. sp. from Poecile sclateri eidos (Peters, 1927); Brueelia juniperi n. sp. from Baeolophus ridgwayi ridgwayi (Richmond, 1902); Brueelia kabulica n. sp. from Sitta tephronota tephronota Sharpe, 1872; Brueelia mpumalangensis n. sp. from Melaniparus niger niger (Vieillot, 1818); Brueelia nazae n. sp. from Parus cinereus caschmirensis Hartert, 1905; Brueelia oxyrhyncha n. sp. from Sitta nagaensis nagaensis Godwin-Austen, 1874; Brueelia picea. sp. from Parus major excelsus Buvry, 1857; Brueelia ragusica n. sp. from Sitta neumayer neumayer Michahelles, 1830; Brueelia regulicida n. sp. from Regulus calendula grinnelli Palmer, 1897; Brueelia sittacola n. sp. from Sitta carolinensis carolinensis Latham, 1790. Brueelia regulicida is the first Brueelia-complex louse to be described from the host family Regulidae. Collectively, the Brueelia of parid, regulid, and sittid hosts show two peculiar patterns. Firstly, lice on closely related hosts appear to be distantly related. Secondly, lice on most hosts in these families appear to be more closely related to lice on other host families than to each other. This contradicts the traditional view that Brueelia-complex lice on closely related hosts are themselves closely related. Potentially, the tendency of the hosts to participate in mixed-species feeding flocks may explain some of these patterns.

RESUMO

Pigeon lice are insects that feed on feathers of these birds; their life cycle includes egg, nymph and adult and they may cause dermatoses in humans. Four persons of the same family, living in an urban area, presented with widespread intensely pruritic erythematous papules. A great number of lice were seen in their house, which moved from a nest of pigeons located on the condenser of the air-conditioning to the dormitory of one of the patients. Even in urban environments, dermatitis caused by parasites of birds is a possibility in cases of acute prurigo simplex. Pigeon lice are possible etiological agents of this kind of skin eruption, although they are often neglected, even by dermatologists.

RESUMO

The increasing capacity of transcriptomic analysis by high throughput sequencing has highlighted the presence of a large proportion of transcripts that do not encode proteins. In particular, long non-coding RNAs (lncRNAs) are sequences with low coding potential and conservation among species. Moreover, cumulative evidence has revealed important roles in post-transcriptional gene modulation in several taxa. In fish, the role of lncRNAs has been scarcely studied and even less so during the immune response against sea lice. In the present study we mined for lncRNAs in Atlantic salmon (Salmo salar) and Coho salmon (Oncorhynkus kisutch), which are affected by the sea louse Caligus rogercresseyi, evaluating the degree of sequence conservation between these two fish species and their putative roles during the infection process. Herein, Atlantic and Coho salmon were infected with 35 lice/fish and evaluated after 7 and 14 days post-infestation (dpi). For RNA sequencing, samples from skin and head kidney were collected. A total of 5658/4140 and 3678/2123 lncRNAs were identified in uninfected/infected Atlantic and Coho salmon transcriptomes, respectively. Species-specific transcription patterns were observed in exclusive lncRNAs according to the tissue analyzed. Furthermore, neighbor gene GO enrichment analysis of the top 100 highly regulated lncRNAs in Atlantic salmon showed that lncRNAs were localized near genes related to the immune response. On the other hand, in Coho salmon the highly regulated lncRNAs were localized near genes involved in tissue repair processes. This study revealed high regulation of lncRNAs closely localized to immune and tissue repair-related genes in Atlantic and Coho salmon, respectively, suggesting putative roles for lncRNAs in salmon against sea lice infestation.

RESUMO

OBJECTIVE: The present study aimed to evaluate scabies and pediculosis cases in the city of Kayseri and to contribute to the epidemiological data in Turkey. METHODS: Data for the present study were obtained from the Kayseri Directorate of Public Health. The distribution of lice and scabies according to age, sex, and years was evaluated retrospectively. RESULTS: A total of 3908 scabies and 4762 pediculosis cases have been reported from the central and peripheral districts of Kayseri between January 2006 and April 2017. It was observed that the number of female cases is higher in both infestations. When positive cases were evaluated according to age, it appears that scabies cases in the 25-44 age group and pediculosis cases in the 10-14 age group are higher. At the same time, in the first 4 months of 2017, it was observed that the number of cases in both infestations was two times higher than that in the previous year. CONCLUSION: We believe that scabies and pediculosis infestations are still a major public health concern in Turkey and its city.

RESUMO

A six-year-old male patient was admitted to our hospital due to itching and scalding crusts that persisted 10-15 days in both eyes. Upon biomicroscopic examination, 5-6 semi-translucent, yellowish brown living lice attached to the upper eyelashes and a large number of eggs were observed. Following application of pilocarpine hydrochloride (Pilomann 2%, Bausch-Lomb) and topical proparacaine hydrochloride (Alcaine 0.5%, Alcon), the paralyzed parasites and eggs were manually removed by pulling with forceps. The lice were identified as adult forms of pubic louse, Pthirus pubis, and its eggs. The patient was treated with pilocarpine hydrochloride, which was applied thrice a day combined with pure vaseline. One week later, no lice or eggs were seen on the eyelashes.

RESUMO

We present this case report to provide information about Felicola subrostratus (Burmeister, 1838) (Phthiraptera: Ischnocera) detected on a 2-year-old stray cat (Felis catus) brought for treatment to a veterinary clinic in Kocaeli, Turkey. Macroscopically, severe louse infestation was detected on the cat. Some of the lice on the cat were collected using forceps and preserved in 70% ethanol. Then, they were sent to Department of Parasitology, Veterinary Faculty, Selçuk University in Konya for identification. Samples were examined under a microscope and identified as F. subrostratus (Burmeister, 1838). F. subrostratus has been known to be detected on cats in Turkey, but no study is found about this species. For this reason, in this case report, F. subrostratus was studied to further educate veterinarians and parasitologists in the country.

RESUMO

Scabies and pediculosis are common parasitic infestations of the skin and hair, manifesting with intense pruritus and effectively treated with modern medications. Because of the attached social stigma linking it with poverty and poor hygiene, patients will often attempt alternative folk-based remedies before confiding in their physicians. We conducted a comprehensive bibliographical study of historic folk literature and interviewed 70 individuals experienced in everyday application of folk medicine in order to categorize available remedies and provide a modern, scientific comment on their effectiveness and dangers. Compositions containing sulfur, copper sulfate, petroleum, coal, tar, and highly alkaline soaps and washing solutions undoubtedly have scabicidal and pediculicidal properties, but they are used either in high concentrations with greater possibility of intoxication and irritation or lower concentrations with questionable therapeutic benefit. These remedies, extracted from historical-cultural frameworks, are poorly adapted to modern standards and can lead to side-effects and complications. Physicians today have to be aware of the reasons their patients seek alternative remedies and know the substances and procedures they may use in self-healing, so as to be able to provide the help that may be needed if those complications occur.
